Compatibility with the latest IDE should be ok, but the latest runtime that is confirmed to work is runtime 2.3.0.401 - there's some change to GameMaker that breaks it afterwards
I will be updating the system Soon™, so that it will work with newer versions - it's a complete rewrite that adds a lot of extra features and performance gains, but I have to find time to work on it between work contracts and such. I do need it for one of my games I'm working on, so it is coming, but it could take 3-12 months before it's ready
Thank you for your interest!
